TORONTO, March 11 (Reuters) - Toronto's main stock market index edged lower on Thursday morning as resource prices slipped and data from the United States and China spurred a return of worry about the stability of the economic recovery.
Miner First Quantum Minerals FM.TO fell 0.3 percent to C$85.61, copper miner Quadra Mining QUA.TO dropped 1.5 percent to C$17.32, and Teck Resources TCKb.TO dropped 1 percent to C$41.17 as base metals prices slid after data showed a spike in Chinese inflation. [METL/]
The market worried the higher Chinese inflation would spawn higher interest rates, which would slow economic activity and demand for resources.
Chinese consumer inflation jumped to a 16-month high in February and a raft of other data displayed broad-based strength, providing fresh arguments for policy tightening sooner rather than later. [ID:nTOE6290B5]
"If the main reason why rates are going up is because they're putting the brakes on things to curb inflation then because China is the big buyer of commodities that would have the impact," said Robert Lauzon, managing director of trading at Middlefield Capital Corporation.
